It is one of the four direct-controlled municipalities of China, with a population of more than 24 million as of 2014. It is a global financial centre, and a transport hub with the world's busiest container port. Located in the Yangtze River Delta in East China, Shanghai sits on the south edge of the mouth of the Yangtze in the middle portion of the Chinese coast. The municipality borders the provinces of Jiangsu and Zhejiang to the north, south and west, and is bounded to the east by the East China Sea. A major administrative, shipping, and trading town, Shanghai grew in importance in the 19th century due to trade and recognition of its favourable port location and economic potential. The city was one of five forced open to foreign trade following the British victory over China in the First Opium War while the subsequent 1842 Treaty of Nanking and 1844 Treaty of Whampoa allowed the establishment of the Shanghai International Settlement and the French Concession. The city then flourished as a center of commerce between China and other parts of the world (predominantly Western countries), and became the primary financial hub of the Asia-Pacific region in the 1930s. However, with the Communist Party takeover of the mainland in 1949, trade was limited to socialist countries, and the city's global influence declined. In the 1990s, the economic reforms introduced by Deng Xiaoping resulted in an intense re-development of the city, aiding the return of finance and foreign investment to the city. Shanghai has been described as the "showpiece" of the booming economy of mainland China; renowned for its Lujiazui skyline, museums and historic buildings, such as those along The Bund, the City God Temple and the Yu Garden.(Photo by Ringo Chiu/PHOTOFORMULA.com)
